I know I can become subjected to hyponatremia by drinking too much water and not replenishing my electrolytes. But is the opposite possible? Can I put too MANY electrolytes into my body (while still putting in the correct amount of fluid) during an endurance event? I once had a Dr. tell me "you can never drink too much gatorade", indicating I would not overload the electrolytes in my body to an unhealthy or dangerous level. Is that true? Do I not have to worry about electrolyte overdose?
UPDATE: I should clarify that I'm asking the question for extreme endurance events, such as 100-mile and 24-hour races.
